PHOTOVOLTAIC COMPOSITIONS OR PRECURSORS THERETO, AND METHODS RELATING THERETO

摘要

A process for forming at least one photovoltaic component on a substrate is described. The substrate comprises a polyimide and a sub-micron filler. The polyimide is derived substantially or wholly from rigid rod monomers and the sub-micron filler has an aspect ratio of at least 3:1. The substrates of the present disclosure are particularly well suited for photovoltaic applications, due at least in part to high resistance to hygroscopic expansion and relatively high levels of thermal and dimensional stability.
